I've often harped on Apple for its policy regarding jailbreaking, but of course, Apple isn't the only company engaging in such practices. We already talked about Motorola, and now, we have Sony - already a company with a checkered past when it comes to consumer rights. As it turns out, Sony don't want you jailbreaking your their Playstation 3.

You're free to do anything with your system,
but the entire content distribution ecosystem is not yours. So you're not supposed to break it.

Hmmm... that's like saying that if I get aboard a bus with a fake ticket, I'm endangering other passengers or the whole service. Well, no.
Sony is ok in policing its busses and checking tickets at their doors (to keep it profitable), but it is not in stopping me on the street to rip my 'worthless' piece of paper.
